ABSTRACT:
A gasoline fraction is catalytically reformed by contacting the gasoline fraction and a hydrogen stream at reforming conditions with an activated bimetallic acidic catalytic composite comprising a combination of a platinum group component, a tin component and a halogen component with a porous carrier material, the catalytic composite having been: (1) activated by contacting same with an activating gas comprising oxygen and a halogenating component selected from the group consisting of halogen and hydrogen halide at a temperature between 700.degree. and 1100.degree. F. for a time of at least 0.5 to about 10 hours; and thereafter (2) reduced by contacting the resulting activated catalytic composite with a substantially water-free reducing agent at reduction conditions selected to reduce substantially all of the platinum group component to the elemental metallic state while maintaining substantially all of the tin component in an oxidation state above that of the elemental metal.
